I have a mac mini connected to a large TV in my lounge room. What I want to be able to do is have finder open in one space (screen/display using expose) and VLC open in another space.

The tricky part I want, though, is to then use another mac to log into the mac mini on the tv via screen sharing. But I only want to see the second space, that is I dont want to see the movie playing from the other space (and waste bandwidth). But then I could simply administer the main space from another mac.
